Most Certifiably Insane Villain (We're Talkin' NUTS, People!)

[WarriorOfMossflower]

Personally, I think it's a threeway tie between Slagar, Cluny, and Gabool.
Slagar, as somebody said before, was clever but delusional. Mostly delusional.
Cluny was also a mastermind to begin with, but he mentally deteriorated over the course of the book. And towards the end I think he became schizophrenic. (Redwall page 327: "The voices had told him he would never again see the warrior after the sun set upon this day.")
Gabool, judging by White One's reasoning on the first page, was definitely and undeniably insane. It's been too long since I read Mariel of Redwall to give much real evidence myself, but I do remember parts such as Gabool throwing his one and only possible maker of the bell he so desired out the window.
But these are just opinions. I think a lot of Redwall villains were never straight in the head.

Edit: *belltower, sorry. I told you my Mariel of Redwall facts are rusty.

[Romsca]

Umm... Rom, you're not a villain, but I think you might be a little insane...

2+2=5

HELP!!! DID I JUST SAY THAT?!

Anyway, I don't think I'm as crazy as Rainy

[The Shade]

Pesonlly I think HiaG is nuts........ anyway back to the topic.

Haha!

[Ferrousferret]

Either Gabool, or the queen from High Rhulain are the winners. I don't think anyone else became a certifiable threat to their own safety.

Vot aboot Gulo ze zavage? 'e vaz juzt aboot entirely mad az vell.

[Tam and Martin]

Vot aboot Gulo ze zavage? 'e vaz juzt aboot entirely mad az vell.

Yes especially when he ate his enemies.

[HeadInAnotherGalaxy]

Cannibalizm iznae quite az mad az ye zink it iz. Zere are zeveral creaturez vho vill eat zere ovn kind.

Gabbol went absolutely crazy, but the worst was Clogg did you hear the way he talked by the end of the book, I wouldn't have been suprised if after he ran out of creatures to bury so he buried himself alive!

[Redwaller]

'e probably could be called vone zough becauze unlezz ah'm miztaken 'e vaz plannin' on eatin' 'iz brozer Askor vho took ze Valkin' Ztone.

He did.

[The Shade]

Then again, the woodlanders are spoken to by Martin (normally just a voice) and they're not crazy...

@The Shade:  His name implies it.

I say Gabool is the most insane one, hands down.

[Rusvul]

Yeah. He went almost suicidal because of a bell. A bell.
